Bootloader on a system partition....

[Lando 0]

...instead of on MBR is an installation option .

But how can be done a boot when bios read on the first track of the first disk ?

Thanks a lot.

the option to install the boot loader on a system partition is for the case when you have already another bootloader in your mbr, which itself can load the bootloader in your system partition, sounds weird but makes sense if you have multiple os on your harddisk.

 

I have grub from my MDV 2008 install in the mbr which then loads the bootloaders of the other distros I have on my harddisk, so I don't risk that I mess up when I install another linux distribution (only if it is one of the silly type which insists on installing into the mbr).

 

If you have only installed Mandriva on your harddisk, you can savely install grub in your mbr, at least on moderately modern hardware.

 

you need to have at least one bootloader in your mbr

Installing the bootloader at the system partition means that you have a primary bootloader present at the MBR (ntloader, another instance of grub, lilo, GaG... and so it goes).

Else it simply is a blunder.
